I've got a Safari that I've been using for a little while and have since expended the cartridge. I got a converter and have a 4oz bottle of Noodler's Baystate Blue that I don't want to waste, but the ink seems like it is not viscous enough for this pen. I've done two fills on the converter and both times it seems the pen is doing okay at first, but after a while of usage there is leakage around the seam between the distributor and the pen body. Is this common for this pen? And is there a better ink (as I was not too fond of the ink in the cartridge that came with it, nor am I a fan of buying tons of cartridges)?
